TL;DR: The Dual Auroral Radar Network (DARN) is a global-scale network of HF and VHF radars capable of sensing backscatter from ionospheric irregularities in the E and F-regions of the high-latitude ionosphere as mentioned in this paper.

TL;DR: In this article, the Kapuskasing and Saskatoon radars of the evolving Super Dual Auroral Radar Network (SuperDARN) HF radar network have been analyzed to study the two-dimensional structure and dynamics of dayside high-latitude ionospheric convection under northward interplanetary magnetic field (IMF) conditions.

TL;DR: In this article, the ducted and partly ducted propagation of artificial VLF waves through the magnetosphere has been studied by means of data from the FR-1 satellite experiment, in which fixed-frequency (16.8 kHz) waves radiated by a transmitter on the ground (at L = 2.1) are received by the satellite at 750 km altitude both in the zone close to the transmitter and in the conjugate zone.

TL;DR: The NetLander mission as mentioned in this paper is the first planetary mission focusing on investigations of the interior of the planet and the large-scale circulation of the atmosphere, which is managed by CNES (the French Space Agency) with other major players being FMI (the Finnish Meteorological Institute), DLR (the German Space Agency), and other research institutes.

TL;DR: In this article, a large number of Doppler spectra obtained at six HF frequencies in the E region with the SHERPA HF radar are analyzed statistically, characterized by their total power, their mean velocity and their spectral width.
